Gouraud shading

In computer animation, technique for calculating the correct colours and intensity of lighting playing on an on-screen three-dimensional object.

Gouraud shading works by measuring the colour and brightness at the vertices of the polygons that make up the object and mixing these to get values for the areas inside the polygons. Specialized hardware makes this process relatively fast. The technique is named after its inventor, Henri Gouraud, and was developed in 1973.
